AMTROL invented the indirect-fired water heater over 30 years ago, redefining the best solution for fast, efficient and reliable hot water. True to their heritage, BoilerMate Hot Water Makers offer great value and dependable performance with options to fit any installation and budget. High Density Poly Bottle withstands aggressive water.

There are two major types of water heaters, those with coils and the twin walled tank. The water heater which we manufacture, the Tank-in-Tank, doesnt fall within either of these categories. The difference between our water heaters and those with coils is clear since in the former the primary fluid heats the domestic hot water from the outside while the other heats it from the inside out. On the other hand the twin walled water heaters have an area near the bottom which is not heated and the heat transfer surface is smaller than in the Tank-in-Tank.
